With its varying short-lived phases, King Crimson is well suited to the box set treatment, and overall, Frame by Frame: The Essential King Crimson doesn't disappoint. At four discs, it's perhaps a little hefty to serve as a comprehensive introduction for newcomers, even though it could work very well in that context; in the end, the box is more of a close-to-definitive package for fans who fall somewhere in between the realms of casual and devoted. The first three discs do an excellent job of summarizing King Crimson's extremely distinct prime-period lineups: the first disc concentrates on the often jazzy symphonic rock of 1969-1971 (including almost the entirety of In the Court of the Crimson King), the second covers the heavy, experimental soundscapes of 1973-1974, and the third features the off-kilter, new wave-influenced prog pop of 1981-1984. The fourth disc is a career-spanning sampler of live Crimson, and although the varying sound quality and musical styles make it a less cohesive listen than the other discs, it does give an excellent idea of the various lineups' extraordinary performing range. Bandleader/compiler Robert Fripp's selections are sometimes skewed toward particular albums, and devotees may cringe at the fact that some of the longer songs have been edited for time, but, in fact, all of this makes for a better, tighter listen; it's difficult to argue with what is here, and the edits often chop out less interesting sections of the pieces. Additionally, the remastering job and the liner notes are both excellent. So, in spite of its minor flaws, Frame by Frame is really everything one could want from a basic King Crimson box set.
